Description This is a rare Eubaculites otacodensis ammonite fossil from the Coniacian stage of the Late Cretaceous period (~89-86 million years ago), discovered in Tulear, Madagascar. Eubaculites is a genus of straight-shelled ammonites, a now-extinct group of marine cephalopods related to modern squid and cuttlefish. Unlike their coiled relatives, Eubaculites had an elongated, uncoiled shell, offering a unique adaptation for buoyancy control in marine environments. Fossils from Tulear, Madagascar, are known for their exceptional preservation, and this Baculites specimen provides valuable insight into Cretaceous marine ecosystems. It is a highly collectible piece for both fossil enthusiasts and scientific study.
